These values are factored in by the BTS equipment internally, leaving
only site specific antenna feed line loss and antenna gain characteristics
to be factored in by the CFE when determining site Effective Radiated
Power (ERP) output power requirements.
Each C–CCP shelf BBX board is optimized to a specific RX and TX
antenna port. (One BBX board acts in a redundant capacity for BBXs
1–12, and is optimized to all antenna ports.) A single value is generated
for each path, thereby eliminating the accumulation of error that would
occur from individually measuring and summing the gain and loss of
each element in the path.
